I have a Sewoo LK-B425A Printer, I have connected it to my PC via USB cable. At the first time plug in, there is no anything in Devices and Printers. Then I unplug the USB and install the divers by CD disk (which included with the printer), after that SEWOO Label Printer display at Printers and also display at Printer queues in Device Manager. Next, I plug the USB again and it shows up as unspecified device as the picture below. Currently if I unplug the USB, LK-B425 device will disappear and I can't print. I only can print if both of devices LK-B425 and SEWOO Label Printer are exist.
Please help me to fix it.
